Abstract: C10H10Cl2Ti was selected as an additive to improve the hydrogen storage properties of the 6LiBH4-CaH2-3MgH2 sample, with optimum hydrogen storage performances by 5%(w/w) addition. The onset and ending temperatures for the dehydrogenation of the sample were 30 and 25℃, which were lower than those of the pristine sample, and its reversible hydrogen storage capacity was about 8.1%(w/w). The desorption rate of the C10H10Cl2Ti-doped sample was 1.78 times faster than that of the pristine sample in the isothermal dehydrogenation mode at 360℃. The apparent activation energy (Ea) of the two-step reaction was calculated to be 131.4 and 138.8 kJ·mol-1, which were 18.6% and 15.8% lower than the pristine sample, respectively. Further XPS analyses indicate that the multivalence state Ti compounds generate during thermal decomposition of C10H10Cl2Ti, which plays an important role to improve the hydrogen storage properties of the 6LiBH4-CaH2-3MgH2 system.
